Best PDF Annotators for Microsoft 365

The Nutrient SDK integrates PDF annotation and markup directly within applications, allowing users to annotate documents on-site rather than exporting them to an external review platform. This tool is utilized by developers, product managers, and document review teams for various tasks such as contract and compliance assessments, board pack reviews, engineering markups, and approval processes. It supports over 15 industry-standard annotation types, including highlights, underlines, strikethroughs, ink drawings, shapes, stamps, sticky notes, and free text, ensuring consistent rendering across web, mobile, and desktop environments. Users can add threaded comments linked to annotations, capturing the author and timestamp, with options to resolve or reopen discussions. Additionally, permission settings determine who can view, comment, or modify annotations. Teams have the ability to personalize colors, toolbars, and stamps, manage annotations through an API, and export in XFDF format for compatibility with other PDF tools or Instant JSON for seamless synchronization across users and devices.
